The Atari 5200 SuperSystem or simply Atari 5200 is a home video game console introduced in 1982 by Atari, Inc. as a higher-end complement for the popular Atari Video Computer System. The VCS was renamed to the Atari 2600 at the time of the 5200's launch. Created to compete with Mattel's Intellivision, the 5200 wound up a direct competitor of ColecoVision shortly after its release. While the Coleco system shipped with the first home version of Nintendo's Donkey Kong, the 5200 included the 1978 arcade game Super Breakout which had already appeared on the Atari 8-bit family and Atari VCS in 1979 and 1981 respectively.
The Atari 7800 ProSystem, or simply the Atari 7800, is a home video game console officially released by Atari Corporation in 1986 as the successor to both the Atari 2600 and Atari 5200. It can run almost all Atari 2600 cartridges, making it one of the first consoles with backward compatibility. It shipped with a different model of joystick from the 2600-standard CX40 and Pole Position II as the pack-in game. Most of the announced titles at launch were ports of 1981–83 arcade video games.
The MOS Technology 6502 is an 8-bit microprocessor that was designed by a small team led by Chuck Peddle for MOS Technology. The design team had formerly worked at Motorola on the Motorola 6800 project; the 6502 is essentially a simplified, less expensive and faster version of that design.
The Atari 8-bit family is a series of 8-bit home computers introduced by Atari, Inc. in 1979 as the Atari 400 and Atari 800. The series was successively upgraded to Atari 1200XL, Atari 600XL, Atari 800XL, Atari 65XE, Atari 130XE, Atari 800XE, and Atari XEGS, the last discontinued in 1992. They differ primarily in packaging, each based on the MOS Technology 6502 CPU at 1.79 MHz and the same custom coprocessor chips. As the first home computer architecture with coprocessors, it has graphics and sound more advanced than most contemporary machines. Video games were a major draw, and first-person space combat simulator Star Raiders is considered the platform's killer app. The plug-and-play peripherals use the Atari SIO serial bus, with one developer eventually also co-patenting USB.
Atari BASIC is an interpreter for the BASIC programming language that shipped with the Atari 8-bit family of 6502-based home computers. Unlike most American BASICs of the home computer era, Atari BASIC is not a derivative of Microsoft BASIC and differs in significant ways. It includes keywords for Atari-specific features and lacks support for string arrays, for example.
BASIC A+ was developed by Optimized Systems Software of Cupertino, California, United States, to provide the Atari 8-bit family with an extended BASIC compatible with the simpler ROM-based Atari BASIC. This interpreter was developed by the same team that developed Atari BASIC. While Atari BASIC came on an 8 KB ROM cartridge, BASIC A+ was delivered on floppy disk and uses 15 KB of the computer's RAM, leaving 23 KB available for user programs in a 48 KB Atari 800. Being an extension of Atari BASIC, BASIC A+ came with a supplement to the former's reference manual as its documentation. In addition to being faster than its ROM-bound counterpart, BASIC A+ provides extra commands for DOS operations, player/missile graphics, and debugging.
The ATASCII character set, from ATARI Standard Code for Information Interchange, alternatively ATARI ASCII, is the variation on ASCII used in the Atari 8-bit family of home computers. The first of this family are the Atari 400 and 800, released in 1979, and later models were released throughout the 1980s. The last computer to use the ATASCII character set is the Atari XEGS which was released in 1987 and discontinued in 1992. The Atari ST family of computers use the different Atari ST character set.
The Television Interface Adaptor (TIA) is the custom computer chip, along with a variant of the MOS Technology 6502 constituting the heart of the 1977 Atari Video Computer System game console. The TIA generates the screen display, sound effects, and reads the controllers. At the time the Atari VCS was designed, even small amounts of RAM were expensive. The chip was designed around not having a frame buffer, instead requiring detailed programming to create even a simple display.
Alphanumeric Television Interface Controller (ANTIC) is an LSI ASIC dedicated to generating 2D computer graphics to be shown on a television screen or computer display. Under the direction of Jay Miner, the chip was designed in 1977-1978 by Joe Decuir, Francois Michel, and Steve Smith for the Atari 8-bit family of home computers first released in 1979 and was patented by Atari, Inc. in 1981. ANTIC is also used in the Atari 5200 video game system released in 1982, which shares most of the same hardware as the 8-bit computers.
Color Television Interface Adaptor (CTIA) and its successor Graphic Television Interface Adaptor (GTIA) are custom chips used in the Atari 8-bit family of computers and in the Atari 5200 home video game console. In these systems, a CTIA or GTIA chip works together with ANTIC to produce the video display. ANTIC generates the playfield graphics while CTIA/GTIA provides the color for the playfield and adds overlay objects known as player/missile graphics (sprites). Under the direction of Jay Miner, the CTIA/GTIA chips were designed by George McLeod with technical assistance of Steve Smith.
Atari DOS is the disk operating system used with the Atari 8-bit family of computers. Operating system extensions loaded into memory were required in order for an Atari computer to manage files stored on a disk drive. These extensions to the operating system added the disk handler and other file management features.
Optimized Systems Software (OSS) was a company that produced disk operating systems, programming languages with integrated development environments, and applications primarily for the Atari 8-bit family of home computers. OSS was best known for their enhanced versions of Atari BASIC and the MAC/65 assembler, both of which are much faster than Atari's products, and the Action! programming language. OSS also sold some products for the Apple II.
AtariWriter is a word processor program for the Atari 8-bit family released by Atari as a 16 kB ROM cartridge in 1983. The program was fast and easy to use, while still allowing the creation of fairly complex documents. It was a huge success for the platform, with at least 800,000 examples sold not including international versions and later updates.
The Parallel Bus Interface, or PBI, is a 50-pin port found on some Atari 8-bit XL computers. It provides unbuffered, direct connection to the system bus lines, running at the same speed as the 6502 CPU. The 600XL and 800XL computers, along with the unreleased 1400XL and 1450XLD had a PBI interface.
Atari MMU is a custom memory management unit chip for the Atari 8-bit computers. It enables access to the hardware registers on ANTIC, GTIA, POKEY and 6520 PIA. The later XL/XE MMU (C061618) also selects OS ROM, Atari BASIC ROM, self-test ROM and LEDs in the 1200XL. On the 128K 130XE the EMMU chip handles similar functionality.
Atari 8-bit computer peripherals include floppy drives, printers, modems, and video game controllers for Atari's 8-bit computer family, which includes the 400/800, XL, XE, and XEGS.
Many pieces of software were available for the Atari 8-bit family of home computers. Software was sold both by Atari, Inc. and third parties. Atari also distributed software through the Atari Program Exchange from 1981 to 1984. After APX folded, many titles were picked up by Antic Software.
MAC/65 is a 6502 assembler written by Stephen D. Lawrow for the Atari 8-bit family of home computers. MAC/65 was first released on disk by Optimized Systems Software in 1982, with the program requiring 16 KB RAM. A bank switched "SuperCartridge" from OSS followed in January 1984 for US$99, occupying only 8 KB.
The XF551 was the last floppy disk drive produced by Atari for the 8-bit series home computers. It was the first drive from the company that officially supported double-density, adding double-sided support, providing 360 kB of storage per disk. It also introduced a faster transfer speed when used in double-density mode, doubling performance. It was packaged in the new gray-colored design language of the XE series computers.
Sierra was the code name for a 16-bit/32-bit personal computer designed by the Sunnyvale Research Lab (SRL) of Atari, Inc. starting around 1983. The design was one of several new 16-bit computer systems proposing to use a new chipset from Atari Corporate Research.
